Principles of bearing selection and application

A bearing-shaft-housing system consists of more than just bearings. Associated components like the shaft and housings are integral parts of the overall system. The lubricant and sealing elements also play a crucial role. To maximize bearing performance, the correct amount of an appropriate lubricant must be present to reduce friction in the bearing and protect it from corrosion. Sealing elements are important because they keep the lubricant in, and contaminants out, of the bearing cavity. This is particularly important since cleanliness has a profound effect on bearing service life. Therefore, SKF manufactures and sells a wide range of industrial seals and lubrication systems.
In this section, and its sub-sections, the designer of a bearing system can find the necessary basic information, presented in the order in which it is generally required. Obviously, it is impossible to include all the information needed to cover every conceivable application. For this reason, in many places, reference is made to the SKF application engineering service. This technical service can perform complex calculations, diagnose and solve bearing performance issues, and help with the bearing selection process. SKF also recommends this service to anyone working to improve the performance of their application.

The information contained in this section and its sub-sections is general and applies to most rolling bearings. Information specific to one bearing type is provided in the relevant product section.
